| Common Name | Undecanoic acid |
|---|
| Description | Undecanoic acid, also known as N-undecylic acid or N-undecanoate, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Undecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Undecanoic acid is a potentially toxic compound. |
